Walking as you go to school, shopping or work is good for your health and it saves money and carbon emissions. But the way American cities are built, some of the folks would benefit most from a little bipedalism live in the areas that make walking the hardest.

That’s the upshot of a complete analysis of the nation’s “built environment,” by a pair of researchers from Duke and the University of Michigan.

Katherine King, a visiting assistant professor in Community and Family Medicine at Duke, worked with Philippa Clarke, an associate research professor in epidemiology at U-M, to examine more than 63,000 census tracts in 48 states and the District of Columbia from the 2000 census.

They used linear regression analysis to look for relationships between five neighborhood characteristics (income, education, race/ethnic composition, age distribution and gender) and five factors that contribute to “walkability,” such as the presence of intersections and building density.

The poorest neighborhoods, and those with the highest education levels — downtown areas of cities –were found to be the most walkable. But census tracts with a higher proportion of children and older adults, the suburbs, were apparently less walkable, with fewer intersections and lower density of street segments.

The authors suggest that urban planners — make that SUB-urban planners —  should give careful thought to the health implications of the living spaces they’re designing. King’s work was supported by the US EPA’s environmental public health division.

500+ Students Code Around The Clock For Social Causes

Tech lovers pull all-night codefest for social good, Nov. 15-16, 2014

More than 500 students converged on Duke’s Fitzpatrick Center for an unusual all-nighter this weekend. No term papers, no problem sets. Their mission: to collaborate on software or hardware projects related to social good. The students were participating in “HackDuke,” the third in a series of 24-hour hackathons held at Duke since 2013.

Checking in at HackDuke: Code for Good

Hacking = Hack + Marathon

To some, “hacking” conjures up images of breaking into bank accounts. But these tech-savvy students are no cyber criminals. The event, dubbed “Code for Good,” challenged them to work in teams to propose tech solutions to problems in any one of four themes — poverty and inequality, health and wellness, education and energy and environment.h2

No experience? No problem

The hacking got rolling around 2 p.m. on Saturday, Nov. 15. Armed with laptops and Ethernet cables, the students fanned out across three floors of the Fitzpatrick Center atrium and got to work. First-time hackers and novice programmers were welcome. Roughly half of this year’s participants were from Duke, and half were from other universities across the United States and Canada. More than 20 percent of the participants were women.h3 h4 h5 h6

A caffeine- and sugar-fueled coding frenzy

The hackers worked non-stop for 24 hours, many with little sleep and no showers. Vast quantities of caffeine and sugar helped. Back by popular demand, after 10 p.m. the CIEMAS basement became a foam-filled battlefield for hackers in need of a nerf gun break:h7 h8 h9

Day 2

Bleary-eyed hackers started presenting their solutions to the judges around 12:30 p.m. on Sunday. One team developed a cloud-based temperature sensor for monitoring premature newborns who are born at home and can’t make it to a clinic. Another team developed an app called “Ananda,” or bliss,which measures the relationship between a range of personal habits and a person’s self-reported happiness score. The winning team from each track received a $750 donation in their name to the nonprofit of their choice. Judge and IBM Program Director Ginny Ghezzo tweeted her favorites:h13 h14h15 h16 h17 h18

His Lab Work Makes Organic Chem More than a “Weed-Out”

By Lyndsey Garcia

“Hey, I ran one of those tests in my lab!” Zach whispered to me during biology lecture. I give him a sideways look, because I definitely didn’t recall running a Southern blot in our assigned lab section. But then I realized that he was referring to the lab that he works in on campus.

Zachary Visco is a sophomore biomedical engineering major on the pre-health track. After hours of hunting through job listings and emailing lab managers, he finally landed a position of working in an ovarian cancer research lab on campus led by Dr. Susan Murphy and Dr. Andrew Berchuck this past summer.

Having only a year of undergraduate education under his belt, he found some of the concepts and techniques in his new job over his head.

“I had no idea what I was doing. I didn’t have any lab experience, but my boss, Dr. Zhiqing Huang, was very patient and walked me through everything,” Zach explained.

As Zach gained more experience in the lab, he started performing more experiments and gaining more responsibility. He would typically perform experiments that ranged from Western Blots, to cDNA preps, to real-time PCR. He was started to gain knowledge of how the pieces worked, but didn’t understand everything behind the science. However, Zach found in his class lectures, he was actually learning about concepts that pertained to his lab.

“Biology has helped explain some of the terminology and processes performed in lab, and organic chemistry has helped explain how and why some of the reactions occur,” he said.

For instance, he learned about the significance of cDNA and the information that can be determined from it. In his lab, he learned that running cDNA preps involved transcribing cDNA from mature RNA in order to perform a real-time PCR. In biology lecture, he learned why his lab would use cDNA instead of normal template DNA because mature RNA only expresses the exon, or the actual genes in our DNA, therefore the cDNA would only express the genes as well.

“I had hoped that I would eventually gain an understanding of the lab work during my undergrad, but when I first started, it all seemed very overwhelming,” Zach said. “I was pleasantly surprised when I found that I could actually apply knowledge from my classes to my work. It made it seem like I was finally learning material that could pertain to my career, not just trying to pass a weed-out class.”

Zach has found that working in the lab and the material taught in his classes has influenced his career path more than he realized. He had previously only imagined himself working in clinic-based research, but is now considering a path in lab-based research.

“I find lab research very interesting because it’s like a puzzle and you are trying to figure out the pieces as you go.”

Duke Forest is Healthy But Vigilant

By Karl Leif Bates

Duke Forest director Sara Childs, left, got into the trees a ways with some of the annual gathering guests.

Duke Forest director Sara Childs, left, got into the trees a ways with some of the annual gathering guests.

The map that Kelly Oten showed at the Duke Forest annual gathering Thursday night could have been a metaphor for the 7,000-acre research and teaching forest itself .

Her map showed the entire state with Duke Forest in the  middle, and advancing legions of forest-killing pests approaching from all sides. In this case, Oten, a forest health monitoring coordinator for the North Carolina Forest Service, was talking about bugs that kill native trees in various horrible ways.

But it might just as well have been a map of encroaching development, rapacious deer, unleashed, freely pooping dogs or any of the dozens of other things that threaten to change the face of  this forested oasis on a daily basis.

In a two-hour meeting with snacks and wine, forest director Sara Childs, her staff and Oten brought a room full of forest-lovers up to date on the current health of Duke’s forested reserve and the status of all kinds of invasive species.  Things are going well, said Childs, who took over this year after the retirement of Judd Edeburn, but the challenges never go away.

Childs said the forest hosted 84 research projects from 23 institutions in the last year. More than 500 students attended class activities — probably a dramatic undercount — and 827 person-hours went into the ambitious overhaul of the heavily used trails and bridges in the Korstian Division.

The biggest blow of the year was the back-to-back ice storms in February and March that disturbed 187 acres in all, 22 of which simply had to be salvage-cut because they were beyond repair, Childs said.

Deer management seems to be helping, Childs said. Ideally, they’d like to see 15-20 of the giant herbivores per square mile, but the count was more like 80 per mile when they started fall culling operations five years ago. The cull is on right now, by the way, closing the Durham, Korstian and Blackwood Divisions Monday through Friday. That’s in effect until Dec. 19, so stay safely away.

Sara Childs presents Judd Edeburn with the plaque for a new division named in his honor. He doesn't get to keep it; it'll be bolted to a very big rock.

At the end of the evening, Childs and the Duke Forest staff showed Edeburn a handsome new brass plaque that will be installed at the entrance to the former Eno division to rename that section of the forest in his honor.

A Made-to-Order Materials Menu

Guest Post by Ken Kingery, Pratt School of Engineering

If you think ordering a drink from Starbucks can be a tall order, try picking out the right material for a new product or experiment. An iced, half-caff, four-pump, sugar-free, venti cinnamon dolce soy skinny latte may be a mouthful, but there are hundreds of thousands of known—and unknown—compounds to choose from, each with their own set of characteristics.

Screenshot of the AFLOW library search interface. The software combs through four giant databases of chemical compounds.

For example, take the family of materials Bi2Sr2Can-1CunO2n+4+x, or bismuth strontium calcium copper oxide for short, if you can call it that. These compounds have the potential to change the world because of their ability to become superconducting at relatively high temperatures. But each sibling, cousin or distant relative has its own physical variations…so how to choose which to pursue?

Thanks to Stefano Curtarolo and his research group, now there’s an app for that.
Curtarolo leads a collection of research groups from seven universities specializing in something they call materials genomics. The group—called the AFLOW consortium—uses supercomputers to comb databases for similar structures and builds theoretical models atom-by-atom to predict how they might behave.

With help from several members of the consortium, Pratt School of Engineering postdocs Cormac Toher, Jose Javier Plata Ramos and Frisco Rose, along with Duke student Harvey Shi, have spent the past few months building a system that combs through four materials databases. Users can choose the elements and characteristics they want a material to have—or not to have—and the website will play matchmaker.

Want a two-element compound containing either silicon or germanium—but not gallium—that is stable enough to withstand high temperatures? Not a problem. How about an electric insulator made from transition metals with a certain crystal structure? AFLOW has you covered.

Stefano Curtarolo

Stefano Curtarolo is a professor of mechanical engineering and materials science at Duke

One of the four databases searched by the program draws from an international collection of compounds with structures known from experimentation. The other three contain single- double- or triple-element compounds, and are not limited to previously explored materials. Through their molecule-building algorithms, the AFLOW consortium is constantly adding prospective materials to these four libraries.

The search engine currently can sort through more than 622,000 known and unknown compounds, and more than 1,000 new ones are added each week. Curtarolo, a professor of materials science and physics, hopes that the open-source program will continue to grow in materials and searchable characteristics to help scientists connect to their ideal material. To see how it works for yourself, take it for a test drive here.

As for an equivalent database of coffee drinks, that has yet to be built. So if you’re looking through AFLOW for a hot, lactose-free drink featuring 150 to 200 mg of caffeine and less than 200 calories made with beans from South America, you’re out of luck.

Fruit flies get their close-up shot, Nobel style

By Robin Ann Smith

Any movie that begins with an extreme close-up of the back side of a fruit fly — the same kind found feeding on over-ripe tomatoes and bananas in your kitchen — may seem like an unlikely candidate for action blockbuster of the year. But this is no typical movie.

Duke biologists Dan Kiehart and Serdar Tulu recorded this 3D close-up of a developing fly embryo using new super-resolution microscope technology developed by Eric Betzig, one of the winners of the 2014 Nobel Prize in Chemistry.

Cutting-edge microscopes available on many campuses today allow researchers to take one or two images a second, but with a new technique called lattice light-sheet microscopy — developed by Betzig and colleagues and reported in the Oct. 24, 2014, issue of Science — researchers can take more than 50 images a second, and in the specimen’s natural state, without smooshing it under a cover slip.

Kiehart and Tulu traveled to the Howard Hughes Medical Institute’s Janelia Farm research campus in Ashburn, Virginia, where the new microscope is housed, to capture the early stages of a fruit fly’s development from egg to adult in 3D.

Fruit fly embryos are smaller than a grain of rice. By zooming in on an area of the fly embryo’s back that is about 80 microns long and 80 microns wide — a mere fraction of the size of the period at the end of this sentence — the researchers were able to watch a line of muscle-like cells draw together like a purse string to close a gap in the fly embryo’s back.

The process is a crucial step in the embryo’s development into a larva. It could help researchers better understand wound healing and spina bifida in humans.

Their movie was assembled from more than 250,000 2D images taken over 100 minutes. The hundreds of thousands of 2D snapshots were then transferred to a computer, which used image-processing software to assemble them into a 3D movie.

“This microscope gives us the highest combination of spatial and temporal resolution that we can get,” Kiehart said.

Betzig won this year’s Nobel Prize for his work on techniques that allow researchers to peer inside living cells and resolve structures smaller than 200 nanometers, or half the wavelength of light — a scale once thought impossible using traditional light microscopes.

Even finer atomic-scale resolution has long been possible with microscopes that use beams of electrons rather than light, but only by killing and slicing the specimen first, so living cells and the tiny structures in motion inside them couldn’t be observed.

Betzig and collaborators Wesley Legant, Kai Wang, Lin Shao and Bi-Chang Chen of Janelia Farm Research Campus all played a role in developing this newest microscope, which creates an image using a thin sheet of patterned light.

The fly movie is part of a collection of videos recorded with the new technology and published in the Oct. 24 Science paper.

One video in the paper shows specialized tubes inside cells called microtubules — roughly 2,000 times narrower than a human  hair — growing and shrinking as they help one cell split into two.

Other videos reveal the motions of individual cilia in a single-celled freshwater creature called Tetrahymena, or cells of a soil-dwelling slime mold banding together to form multicellular slugs.

Kiehart and Tulu will be going back to Janelia Farm in January to use the microscope again.

“For this visit we’re going to zoom in to a smaller area to look at individual cells,” Tulu said.

“Waking up the morning of October 8 and hearing on the radio that our paper includes a Nobel Prize winner was pretty special,” Kiehart said.

Shedding Light on Careers Beyond Academia  

Grad school can seem like walking down a well-lit path in an otherwise dark forest. It’s easy to see the academic path, but who knows what might happen if you step off of it? (Illustration: Ted Stanek)

Guest post from Ted Stanek, PhD candidate in neurobiology

The Duke Institute for Brain Sciences’ Beyond Academia panel on Oct. 30 tried to illuminate the many career paths available to PhDs and spread hope rather than dread in the minds of Triangle area graduate students.

There has been a flood of articles recently about the increase in competition in the academic world for tenure-track faculty positions and federal funding. They all harped on the perils of staying in academia and the tragedy of being a PhD student or postdoc in such a climate.

Many of these stories focus on the terrifying choice that all PhDs and postdocs face at various points in their career: whether or not they want to stay on the academic track. The alternative feels like jumping off of a cliff, and many people complain that programs which accept more PhD students than there are academic jobs available are effectively pushing students towards that cliff.

Ted Stanek

Ted Stanek is a PhD student in neurobiology.

In the face of this negative outlook for PhDs, the Duke Institute for Brain Sciences recently provided welcome insight into the variety of non-academic careers that may lie in a PhD’s future. Beyond Academia was a day-long workshop consisting of five groups of 3-4 panelists discussing their own career trajectories, what their careers are like, and how they prepared to achieve such positions. Each panelist had a neuroscience or biomedical science PhD, and each had found a successful and fulfilling career outside of the academic niche.

“There are no ‘alternative careers’,” Katja Brose, Senior Editor of Neuron, emphasized in her keynote address.  “There are just careers.”

Workshop panelists revealed just how many careers were available to PhDs. A major point reinforced during the event was that you are never “stuck” on the academic track. You have the option of changing careers every step of the way – even after you’ve reached the level of tenured faculty.

Switching career paths, however, is a daunting task – a common reason why many PhD students go straight into a postdoc. It’s easy to see how the skills that you learn as a graduate student will transfer to skills you can use as a postdoc, and then as a young faculty.

Elizabeth Brannon, a professor of psychology & neuroscience who organized the seminar, pointed out in her welcoming speech that PhD students have limited access to professionals outside of academia, making it difficult to even identify non-academic careers that may interest them, let alone prepare for them.

While many of these careers beyond academia do require some type of preparation, this preparation may simply consist of pursuing your interests while completing your PhD. Writing or editing for your lab, starting up a journal club, and participating in university or professional organizations are all great ways to boost your resume and develop your interests.

Perhaps the hardest part of preparing for any career, academic or otherwise, is undergoing that initial period of self-reflection necessary to identify what skills you possess in your current position, what interests you about your job, and how your life values might impact your career.

“The point at which your skills, interests, and values overlap determines your career sweet spot,” Brose said.

Do you especially enjoy the administrative aspects of academia? Maybe grant management is the way to go. How about actually conducting experiments to discover new biological mechanisms? Perhaps working in a pre-clinical lab for a pharmaceutical company is the place for you. What if you love writing – either the spinning of a story (science writer/freelancer), or writing down the scientific facts with precise and accurate language (medical writer)? Are you interested in new biological technology (intellectual property and patent law)? Or helping to change laws about science (science policy)? Maybe you just love reading papers and debating where they should be published (journal editor).

All of these positions highly value PhDs in particular, no matter what the specifics of your thesis are. Every PhD in the brain and behavioral sciences, whether molecular, systems, or behavioral, develops what career advisors call transferable skills. These highly valued “super powers” as one panelist put it, include being able to communicate technical topics to a diverse audience, working with team members, learning a large amount of information quickly and effectively, being resilient in the face of unexpected adversity, and thinking critically to solve complex problems. The overwhelming message from Beyond Academia was that no matter where you end up, after you get your PhD you can find a career that will make you happy and fulfilled.

To me, it seems like pursuing a PhD is a lot like walking down a well-lit path in an otherwise dark forest. It’s easy to see the next step along the path to academia, but who knows what might happen if you step off of it?

Thanks to Beyond Academia, that forest is now a little brighter.

Beyond Academia was  presented by the Duke Institute of Brain Sciences, the Graduate Admitting Program in Cognitive Neuroscience, the Neurobiology Graduate Program, and the Duke Psychology & Neuroscience Graduate Program.  This event was organized by  Elizabeth Brannon and Richard Mooney, with help from Tanya Schrieber, and moderated by Duke graduate students Caroline Drucker, Rosa Li, Marissa Gamble, and Vanessa Puñal.

The Science of Self-Agency: Dr. Nicolelis and the Walk Again Project

By Olivia Zhu

Screen grab from Univision of Juliano’s robo-kick at the World Cup opening ceremony.

Over the course of his 20-year career, Dr. Miguel Nicolelis has restored movement and self-agency to paraplegic patients.

On November 11th, as part of the Grand Challenge Seminar Series, Dr. Nicolelis captivated his audience by explaining the extensive process that culminated in Juliano, a Brazilian 29-year-old paralyzed from the chest downward in a car accident, performing the opening kick of the World Cup simply by using his mind.

Dr. Nicolelis has several faculty appointments in the Duke School of Medicine, Department of Psychology and Neuroscience, Institute for Brain Sciences, and Center for Neuroengineering. He has also written a book, Beyond Boundaries, about his work. His program, Walk Again, is supported by the Edmond and Lily Safia International Institute of Neuroscience in Brazil.

Dr. Nicolelis began making progress in 1999-2000 at Duke by developing electrodes that could record firing from multiple neurons. Using this technology, he determined which neurons were necessary for a monkey to move a joystick during a video game. Then, Dr. Nicolelis focused on creating a bypass that would bridge the mind directly to a computer, essentially removing the body as an intermediary.

He called this bypass a “Brain-Machine Interface,” or BMI, a term he coined at a cheese steak joint outside of Philadelphia. With the BMI, Dr. Nicolelis’s monkeys could play the video game without moving their arms or the joystick—they simply imagined themselves moving the joystick. The monkeys could even use their arms to do other tasks like eat or scratch themselves, creating a “third arm.”

Since then, with an extensive team of engineers, Dr. Nicolelis has implemented this technology by creating a IMG_1941hydraulically-powered exoskeleton that interprets a patient’s firing neurons and moves a patient’s legs accordingly.

He has also created artificial “skin,” which provides tactile feedback of movement to a patient’s upper body or, eventually, through an implant directly to the tactile cortex of the brain.

The technology is so accurate that patients report feeling “ghost limbs”—they believe that their legs are actually walking. The legendary Brazilian soccer player, Ronaldo, reportedly exclaimed “I’m moving!” with incredulity, when he was strapped to a chair testing Nicolelis’s technology.

Training with the exoskeleton also improves patients’ cardiovascular circulation, mental health, gastrointestinal health, and sensitivity in previously paralyzed areas.

Dr. Nicolelis is truly using science to stretch the boundaries of the human body.

World Domination in a Loaf of Bread

By Robin Smith

If baker’s yeast could take over the world, the bread leavener’s world domination might look like this time-lapse movie produced by a team led by Duke biologist Nicolas Buchler:

Their report in the Nov. 5, 2014, issue of the journal Molecular Biology of the Cell shows time-lapse images of yeast cells under a microscope as one cell grows and divides into two, and two into four, and so on.

To watch the budding yeasts in action, the researchers inserted a gene for an enzyme that gives fireflies their characteristic yellow light into the yeasts’ DNA.

It normally takes one yeast cell about 90 minutes to grow and divide into two new cells. But in the time-lapse movie, the process is compressed into a few seconds.

The yellow dots show genes being turned on and off in the nucleus of each cell.

The approach allows scientists to track the activation and deactivation of genes over a tiny cell’s fast life cycle more accurately than standard labeling techniques using other glowing proteins, the researchers say.

All Ears for Corn Genetics

By Nonie Arora

“Technology is progress” and “new is better” seem to be mantras in some fields of research. However, when it comes to fields of genetically modified corn, we might be wise to think otherwise.

Duke biology professor Dr. Mary Eubanks spoke to a group of Duke students, community members, and a farmer from Togo about corn genetics in a workshop held Friday, Oct. 24 at the Duke Campus Farm. Dr. Eubanks founded her own seed genetics company (Sun Dance Genetics LLC) and is a leading advocate for changing the way we grow corn.

Dr. Eubanks became intrigued by the origins of corn while studying the origins of agriculture and the start of American civilization in an archaeology PhD program. She realized that she wouldn’t be able to answer her questions about what she considered to be this “great botanical mystery” without an understanding of genetics. To uncover this mystery, she pursued a postdoctoral program in corn genetics. Based on her experimentation, she developed the hypothesis that maize domestication involved something called intergeneric hybridization, or crossing between plants in different genera.

During her career, Dr. Eubanks also worked in regulatory affairs and learned about the devastating effects of chemical pesticides. She became an advocate for sustainable agriculture: finding ways to develop pest-resistant corn without genetic engineering. She has successfully transferred natural resistance to the worst insect pests of corn — corn rootworm and European corn borer.

In contrast to using natural breeding methods to create new lines of corn, genetically modifying organisms could have negative effects on human health, according to Dr. Eubanks. Dr. Eubanks believes that the inserter and promoter sequences that are used to get the genes to express the foreign proteins can lead to antibiotic resistance and intestinal issues for humans.

The group was surprised by her description of her own anaphylactic shock reaction to Bt-corn, a GMO. Her own personal history of the allergic reaction made her think of the potential reactions our bodies could be having to GMOs. Dr. Eubanks described how it was problematic that genes being introduced to the crop came from other organisms and that humans haven’t evolved a tolerance to the proteins the genes encode. This could lead to potential allergenicity in humans. According to Dr. Eubanks, it is possible that there has been horizontal gene transfer between plasmids — small molecules used to insert genes from one organism to the next — and the human gut.

When asked about the regulations regarding GMOs, Dr. Eubanks explained that the FDA is in charge of the labeling and GMOs are generally regarded as safe so long as they are substantially equivalent to the other food product. The industry is very opposed to the labeling of GMOs and 90% of the corn, cotton, and soy available has some GMO product in it, according to Dr. Eubanks. She believes that not enough is being done to regulate the industry.

We were intrigued by her discussion of food security and funding for interventions. She described that a lot of international work on food security highly promotes technology and the big industry agricultural model. Dr. Eubanks believes we need to change our paradigm from thinking that the most advanced technological options are always best to considering an ecological intensification approach. Such an approach seeks to design more productive, sustainable production systems that are well suited to their environments by better understanding how nature functions. Her current work is helping bring food security to South Sudan through corn that is pest-resistant and drought-tolerant.


Kumbaya and All That… Until Thursday!

By Karl Leif Bates

You wouldn’t know it from the war drums banging over at ESPN this week in advance of Thursday night’s football showdown, or the hairy eyeball the frat boys give you for wearing the wrong shirt in Chapel Hill, but our two fine institutions, Duke and UNC-Chapel Hill, are actually very good friends and close collaborators. …At the faculty level, at least.

It’s quite common for a major research paper coming out of either campus to include collaborators from the other Tier 1 research university just 10 miles away. It only makes sense. When the ARRA Stimulus funding was on the table a few years ago, the two pulled together on all sorts of projects to bring about $400 million in federal tax dollars back to the Triangle.

And now, a new program announced just a few weeks ago will actually pay researchers from both schools to be friends! Can you imagine?

A Chapel Hill taunt. (Not actually supported by the data, but whatever.)

A Chapel Hill taunt. (Not actually supported by the data, but whatever.)

Duke’s Translational Medicine Institute (DTMI) and the North Carolina Translational and Clinical Sciences Institute (NC TraCS) are awarding $50,000 grants to research projects that are trying to speed laboratory medical findings into the clinic or the population. (That’s what “translation” means.) The only catch is that the application has to include one co-investigator from each school.

“I think that although we come from different ends of Tobacco Road and our different shades of blue compete passionately in sports, when it comes to translating medical progress and health care to the community, we can be very collaborative,” Jennifer Li of the Duke Translational Medicine Institute told the DTMI newsletter.

Just look at those long faces! Poor kids. A Duke buzzer-beater will do that to you.

Just look at those long faces! Poor kids. A Duke buzzer-beater will do that to you.

Naturally, the newsletter then had to quote a Tarheel: “On a scientific basis, collaborative teams are formed based on shared interests and complimentary resources, skills and experiences,” said John Buse, deputy director of the NC Translational and Clinical Sciences Institute. “The hope (is) that the sum is greater than the parts.”

Perhaps, Dr. Buse, perhaps. But what’s the fun in that?
